Abstract

?????????????????????????? ??????/???????????????????????????????????????????n-1???????n??2?8????? ???????????????????????????????????????????????????????????????????????? ????????????????????????????????????????????????????????????? tradução do resumo resumo patente de invenção: "fornalha de craqueamento de etileno". trata-se de uma fornalha de craqueamento de etileno que compreende: pelo menos uma região de radiação na qual um queimador inferior e/ou um queimador de parede lateral é instalado; e pelo menos um conjunto de tubos de fornalha de radiação disposto ao longo de uma direção longitudinal da região de radiação. a fornalha de radiação compreende pelo menos dois segmentos de tubo de fornalha que tem uma estrutura do tipo n-1, em que n é, de preferência, um número natural entre 2 e 8. é fornecido um tubo coletivo na extremidade inferior do tubo de fornalha no segmento a jusante dos pelo menos dois segmentos de um tubo de fornalha. a extremidade inferior do tubo de fornalha no segmento a montante dos pelo menos dois segmentos de tubo de fornalha está conectada ao tubo coletivo através de um conector curvo. por meio dessa configuração, reduz-se a tensão existente nos tubos de fornalha, devido à desigualdade de expansão entre os tubos de fornalha no primeiro segmento e a diferença de expansão entre os segmentos a montante e a jusante dos tubos de fornalha, evitando, assim, que os tubos de fornalha se flexionem e prolongando a vida útil dos tubos de fornalha de radiação.
